Abstract
A forming mold made from a polyporous refractory material is provided for forming a glass piece. The forming mold includes an outer surface and a plurality of forming structures provided on the outer surface. Each of the forming structures includes a forming surface matching with a shape of the glass piece. The forming mold is structured and arranged to be pumped down from the outer surface to generated an absorption force on molten glass material provided at the at least one forming surface for sucking the molten glass material on the forming structure to form the glass piece.
Claims16
A forming mold for forming a glass piece, the forming mold comprising:
- an outer surface;
- and
- a forming structure provided at the outer surface;
- wherein the forming mold is made from a polyporous refractory material, the forming structure comprises at least one forming surface matching with a shape of the glass piece, the forming mold defines a plurality of micro-cavities communicating with each other in interior of the forming mold and the outer surface of the forming mold, the micro-cavities are evenly and compactly distributed in the forming mold, and the forming mold is structured and arranged to be pumped down from the outer surface to generate an absorption force on molten glass material provided at the at least one forming surface for sucking the molten glass material on the forming structure to form the glass piece.
A forming device for forming a glass piece, the forming device comprising:
- at least two forming chambers connected one by one along a predetermined path;
- a forming mold;
- a vacuum pump operatively connected to the forming mold;
- and
- a transmission mechanism configured to transmit the forming mold through the different forming chambers along the predetermined path;
- wherein the forming mold is made from a polyporous refractory material and comprises an outer surface and a forming structure provided at the outer surface, the forming structure comprises at least one forming surface, the forming mold defines a plurality of micro-cavities communicating with each other in interior of the forming mold and the outer surface of the forming mold, the micro-cavities are evenly and compactly distributed in the forming mold, the vacuum pump is configured to pump down the forming mold to generate an absorption force on molten glass material provided at the at least one forming surface for sucking the molten glass material on the forming structure to form the glass piece.
